1. What will 5G be?目前引用量：4189 作者：
英文摘要： What it will not be is an incremental advance on 4G. The previous four generations of cellular technology have each been a major paradigm shift that has broken backwards compatibility. And indeed, 5G will need to be a paradigm shift that includes very high carrier frequencies with massive bandwidths, extreme base station and device densities and unprecedented numbers of antennas. But unlike the previous four generations, it will also be highly integrative: tying any new 5G air interface and spectrum together with LTE and WiFi to provide universal high-rate coverage and a seamless user experience. To support this, the core network will also have to reach unprecedented levels of flexibility and intelligence, spectrum regulation will need to be rethought and improved, and energy and cost efficiencies will become even more critical considerations. This paper discusses all of these topics, identifying key challenges for future research and preliminary 5G standardization activities, while providing a comprehensive overview of the current literature, and in particular of the papers appearing in this special issue. 中文摘要： 它不會是4G的逐步推進。前四代蜂窩技術(shù)都是一個主要的范式轉(zhuǎn)變，已經(jīng)破壞了向后兼容性。事實上，5G將需要成為一種范式轉(zhuǎn)變，其中包括具有大量帶寬的極高載波頻率，極端基站和設(shè)備密度以及前所未有的天線數(shù)量。但與前四代不同，它也將是高度集成的：將任何新的5G空中接口和頻譜與LTE和WiFi連接在一起，以提供通用的高速覆蓋和無縫的用戶體驗。為了支持這一點，核心網(wǎng)絡(luò)還必須達到前所未有的靈活性和智能水平，頻譜監(jiān)管需要重新考慮和改進，能源和成本效率將成為更加重要的考慮因素。本文討論了所有這些主題，確定了未來研究和初步5G標準化活動的主要挑戰(zhàn)，同時全面概述了當前的文獻，特別是本期特刊中出現(xiàn)的論文。 2.Millimeter wave mobile communications for 5G cellular: It will work!目前引用量：3441 作者：
英文摘要： The global bandwidth shortage facing wireless carriers has motivated the exploration of the underutilized millimeter wave (mm wave) frequency spectrum for future broadband cellular communication networks. There is, however, little knowledge about cellular mm-wave propagation in densely populated indoor and outdoor environments. Obtaining this information is vital for the design and operation of future fifth generation cellular networks that use the mm-wave spectrum. In this paper, we present the motivation for new mm-wave cellular systems, methodology, and hardware for measurements and offer a variety of measurement results that show 28 and 38 GHz frequencies can be used when employing steerable directional antennas at base stations and mobile devices. 中文摘要： 無線運營商面臨的全球帶寬短缺促使未來寬帶蜂窩通信網(wǎng)絡(luò)探索未充分利用的毫米波（mm波）頻譜。 然而，對于人口密集的室內(nèi)和室外環(huán)境中的細胞毫米波傳播知之甚少。 獲取此信息對于使用毫米波頻譜的未來第五代蜂窩網(wǎng)絡(luò)的設(shè)計和操作至關(guān)重要。 在本文中，我們介紹了用于測量的新型毫米波蜂窩系統(tǒng)、方法和硬件的動機，并提供了各種測量結(jié)果，顯示在基站和移動設(shè)備上采用可操縱定向天線時可以使用28和38GHz頻率。 3.Five Disruptive Technology Directions for 5G 目前引用量：2142 作者：

This paper describes five technologies that could lead to both architectural and component disruptive design changes: device-centric architectures, millimeter Wave, Massive-MIMO, smarter devices, and native support to machine-2-machine. The key ideas for each technology are described, along with their potential impact on 5G and the research challenges that remain. 中文摘要： 新的研究方向?qū)?dǎo)致未來第5代（5G）蜂窩網(wǎng)絡(luò)設(shè)計的根本變化。 本文介紹了可能導(dǎo)致架構(gòu)和組件破壞性設(shè)計變更的五種技術(shù)：以設(shè)備為中心的架構(gòu)，毫米波，Massive-MIMO，更智能的設(shè)備以及對machine-2-machine的本機支持。 描述了每種技術(shù)的關(guān)鍵思想，以及它們對5G的潛在影響以及仍然存在的研究挑戰(zhàn)。 4. Millimeter-wave beamforming as an enabling technology for 5G cellular communications: theoretical feasibility and prototype results 目前引用量：1392 作者：
英文摘要： The ever growing traffic explosion in mobile communications has recently drawn increased attention to the large amount of underutilized spectrum in the millimeter-wave frequency bands as a potentially viable solution for achieving tens to hundreds of times more capacity compared to current 4G cellular networks. Historically, mmWave bands were ruled out for cellular usage mainly due to concerns regarding short-range and non-line-of-sight coverage issues. In this article, we present recent results from channel measurement campaigns and the development of advanced algorithms and a prototype, which clearly demonstrate that the mmWave band may indeed be a worthy candidate for next generation (5G) cellular systems. The results of channel measurements carried out in both the United States and Korea are summarized along with the actual free space propagation measurements in an anechoic chamber. Then a novel hybrid beamforming scheme and its link- and system-level simulation results are presented. Finally, recent results from our mmWave prototyping efforts along with indoor and outdoor test results are described to assert the feasibility of mmWave bands for cellular usage. 中文摘要： 移動通信中不斷增長的流量爆炸最近引起了對毫米波頻帶中大量未充分利用頻譜的關(guān)注，作為與當前4G蜂窩網(wǎng)絡(luò)相比實現(xiàn)數(shù)十倍至數(shù)百倍容量的潛在可行解決方案。從歷史上看，mmWave頻段被排除用于蜂窩使用，主要是由于對短距離和非視距覆蓋問題的擔憂。 在本文中，我們介紹了通道測量活動的最新結(jié)果以及高級算法和原型的開發(fā)，這清楚地表明mmWave波段可能確實是下一代（5G）蜂窩系統(tǒng)的有用候選者?？偨Y(jié)了在美國和韓國進行的信道測量的結(jié)果以及在消聲室中的實際自由空間傳播測量。然后提出了一種新穎的混合波束形成方案及其鏈路和系統(tǒng)級仿真結(jié)果。最后，我們的mmWave原型制作以及室內(nèi)和室外測試結(jié)果的最新結(jié)果被描述為斷言mmWave頻帶用于蜂窩使用的可行性。 5. Scenarios for the 5G Mobile and Wireless Communications: the Vision of the METIS Project 目前引用量：1325 作者：
英文摘要： METIS (Mobile and wireless communications Enablers for the Twenty-twenty Information Society) is the EU flagship 5G project having the objective to lay the foundation for 5G systems and to build consensus prior to standardization. The METIS overall approach towards 5G builds upon the evolution of existing technologies complemented by new radio concepts that are designed to meet the new and challenging requirements of use cases today's radio access networks cannot support. The integration of these new radio concepts such as Massive MIMO, Ultra Dense Networks, Moving Networks, Device-to-Device, Ultra Reliable, and Massive Machine Communications will allow 5G to support the expected increase in the mobile data volume while broadening the range of application domains that mobile communications can support beyond 2020. In this paper, we describe the scenarios identified for the purpose of driving the 5G research direction. Further, we give initial directions for the technology components (such as link level components, multi node/multi antenna, multi-RAT (Radio Access Technology) and multi-layer networks and spectrum handling) that will allow fulfilling the requirements of the identified 5G scenarios. 中文摘要： METIS是歐盟旗艦5G項目，其目標是為標準化之前的5G系統(tǒng)奠定基礎(chǔ)并建立共識。 METIS針對5G的整體方法建立在現(xiàn)有技術(shù)發(fā)展的基礎(chǔ)上，輔以新的無線電概念，旨在滿足當今無線接入網(wǎng)絡(luò)無法支持的用例的新的和具有挑戰(zhàn)性的要求。這些新的無線電概念的集成，如大規(guī)模MIMO，超密集網(wǎng)絡(luò)，移動網(wǎng)絡(luò)，設(shè)備到設(shè)備，超可靠和大規(guī)模機器通信將允許5G支持移動數(shù)據(jù)量的預(yù)期增長，同時擴大范圍移動通信可以在2020年之后支持的應(yīng)用領(lǐng)域。 在本文中，我們描述了為推動5G研究方向而確定的方案。此外，我們?yōu)榧夹g(shù)組件（如鏈路級組件，多節(jié)點/多天線，多RAT（無線接入技術(shù)）和多層網(wǎng)絡(luò)和頻譜處理）提供初步指導(dǎo)，以滿足已確定的5G的要求場景。 6. Cellular Architecture and Key Technologies for 5G Wireless Communication Networks 目前引用量：1311 作者：
英文摘要： The fourth generation wireless communication systems have been deployed or are soon to be deployed in many countries. However, with an explosion of wireless mobile devices and services, there are still some challenges that cannot be accommodated even by 4G, such as the spectrum crisis and high energy consumption. Wire- less system designers have been facing the continuously increasing demand for high data rates and mobility required by new wireless applications and therefore have started research on fifth generation wireless systems that are expected to be deployed beyond 2020. In this article, we propose a potential cellular architecture that separates indoor and outdoor scenarios, and discuss various promising technologies for 5G wireless communication systems, such as massive MIMO, energy-efficient communications, cognitive radio networks, and visible light communications. Future challenges facing these potential technologies are also discussed. 中文摘要： 第四代無線通信系統(tǒng)已在許多國家部署或即將部署。然而，隨著無線移動設(shè)備和服務(wù)的激增，仍然存在一些即使是4G也無法滿足的挑戰(zhàn)，例如頻譜危機和高能耗。無線系統(tǒng)設(shè)計人員一直面臨著對新無線應(yīng)用所需的高數(shù)據(jù)速率和移動性的不斷增長的需求，因此已經(jīng)開始研究預(yù)計將在2020年之后部署的第五代無線系統(tǒng)。 在本文中，我們提出了一個將室內(nèi)和室外場景分開的蜂窩架構(gòu)，并討論5G無線通信系統(tǒng)的各種有前景的技術(shù)，例如大規(guī)模MIMO，節(jié)能通信，認知無線電網(wǎng)絡(luò)和可見光通信。還討論了這些潛在技術(shù)面臨的未來挑戰(zhàn)。 7. Network Densification: The Dominant Theme for Wireless Evolution into 5G 目前引用量：1098 作者：
英文摘要： This article explores network densification as the key mechanism for wireless evolution over the next decade. Network densification includes densification over space (e.g, dense deployment of small cells) and frequency (utilizing larger portions of radio spectrum in diverse bands). Large-scale cost-effective spatial densification is facilitated by self-organizing networks and inter- cell interference management. Full benefits of network densification can be realized only if it is complemented by backhaul densification, and advanced receivers capable of interference cancellation. 中文摘要： 本文探討了網(wǎng)絡(luò)密集化作為未來十年無線演進的關(guān)鍵機制。網(wǎng)絡(luò)密集化包括空間致密化（例如，小小區(qū)的密集部署）和頻率（利用不同頻帶中較大部分的無線電頻譜）。自組織網(wǎng)絡(luò)和小區(qū)間干擾管理促進了大規(guī)模經(jīng)濟有效的空間密集化。只有在回程密集化和能夠干擾消除的高級接收器的補充下，才能實現(xiàn)網(wǎng)絡(luò)密集化的全部好處。 |
